To meet the requirements of digital photography, the Leica Super-Elmar-M 21mm/3.4 ASPH is a benchmark in all optical performance characteristics. The stray light optimization was implemented on a very high level, allowing for backlit shots with crystal clear contrast. The design of the metal lens hood matches the appearance of the current wide-angle lenses of the Leica M system. This lens hood is also compatible with the Leica Super Elmar-M 24 mm/3.8 ASPH and the Leica Super Elmar-M 35mm/1.4. With the Leica M8 and M8.2, the Leica Super-Elmar-M 21mm/3.4 ASPH has an equivalent focal length of 28 mm making it a practical standard wide-angle lens for use with the Leica M8 and M8.2. For optimal use of the Leica Super-Elmar-M 21mm/f3.4 ASPH, firmware updates for the M8, M8.2 and M9 are available.

The performance of the Leica Super-Elmar-M 21 mm f/3.4 ASPH. is reminiscent of one of the all-time favorite classic M lenses, the Leica Super-Angulon-M 21 mm f/3.4. This highly praised lens was an integral part of the Leica M lens portfolio from 1963 to 1980 and made its name and reputation as an ideal tool for available light photography and photojournalism. Even today, the Super-Angulon-M 21 mm f/3.4 remains extremely popular and one of the most sought-after M lenses amongst connoisseurs of fine optics.

The new Leica Super-Elmar-M 21 mm f/3.4 ASPH. is a worthy successor, with further improvements over the already outstanding performance of its forerunner model. The lens reveals its excellent reproduction of detail and superior contrast at maximum aperture. Of particular note is the extremely effective optimization of flare characteristics of the Leica Super-Elmar-M 21 mm f/3.4 ASPH., which allows the capture of fascinating ‘contre-jour’ images with absolute clarity and contrast.

The intricate optical design and construction of the lens are responsible for its outstanding sharpness and imaging qualities. The Leica Super-Elmar-M 21 mm f/3.4 ASPH. is constructed with eight lenses in seven groups. At the same time, the use of one lens element with two aspherical surfaces and four lenses with anomalous partial dispersion ensure that aberrations are reduced to an absolute minimum.

As with all Leica lenses, the Super-Elmar-M 21 mm f/3.4 ASPH. was designed and developed by Leica specialists in Solms, Germany and represents the perfect combination of optical and technical expertise. Particularly reliable and with enduring value, every Leica lens is manufactured from only the highest quality materials and is assembled with meticulous precision, completely by hand. The combination of cutting-edge technologies and extremely thorough manufacturing processes guarantees consistently excellent quality.

The Leica Super-Elmar-M 21 mm f/3.4 ASPH. is supplied with a high-quality, all-metal lens hood, which should be mounted at all times. The hood not only protects the lens effectively against reduction of contrast by extraneous light, but also against damage and the accumulation of dirt on the front lens element.

The Leica Super-Elmar-M 21mm f/3.4 ASPH. will be available from Leica dealers beginning July 2011.
